Patented May 1 8 193'? UNITED STATES PATENT OFFICE OPHTHALMIC MOUNTINGApplicationJulylS, 1936, Serial No. 90,673 6 Claims. (o1. 88-53) Thisinvention relates, generally, to ophthalmic mountings, and the inventionhas reference, more particularly, to means for adjustably connecting thelenses of spectacles and eyeglasses to the temples thereof. 7

Heretofore, temple end pieces used in connection with spectacles andeyeglasses merely provided a hinged connection between the lenses orlens rims and the temples, no means being provided for adjusting thetemples with respect to the lenses or lens rims to facilitate thefitting of the eyeglasses, and such fitting could only be accomplishedby bending the temples which is undesirable and generally results inimproper fitting of the eyeglasses.

The principal object of the present invention is to provide a novelconstruction of temple end piece that enables the universal adjustmentof the temple with respect to the lens or lens rim, thereby enabling theoptician to readily and accurately fit the eyeglasses to the head of thewearer, means being provided for locking the temple end piece yoke inadjusted position with respect to the temple end piece lens strap,whereby the proper positional relation between the temple hinge and thelens will always be maintained thereafter.

Another object of the present invention is to provide a temple end piececonstruction that is suitable for attachment to any point along theperiphery of the lens, the universal adjustment of the end pieceenabling such attachment.

Still another object of the present invention is to provide a novelophthalmic temple end piece construction that is neat and attractive inappearance, that is of rugged construction and reliable in use.

Other objects of this invention, not at this time more particularlyenumerated, will be clearly 40 understood from the following detaileddescription of the same.

The invention is clearly illustrated in the accompanying drawing, inwhich:

Fig. 1 is a view in front elevation of a pair of 45 spectacles equippedwith the novel temple end piece construction of this invention.

Fig. 2 is a fragmentary view in plan showing the adjustable nature ofthe end piece construction.

Fig. 3 is an enlarged transverse part sectional view of the structureshown in Fig. 2.

Fig. 4 is a view similar to Fig. 2, but of a somewhat modifiedconstruction.

Fig. 5 is a view in elevation with parts broken away of the structureshown in Fig. 4.

Fig. 6 is a fragmentary view in front elevation of the structure shownin Figs. 4 and 5.

Similar characters of reference are employed in said views, to indicatecorresponding parts.

Referring now to Figs. 1 to 3 of the said drawing, the reference numeralI designates a pair of spectacles shown as of the rimless type andhaving lenses 2 that are interconnected by the mounting or bridge member3 in the usual manner. Bridge member 3 has depending arms or yokes 4, tothe lower ends of which are integrally or otherwise connected lensstraps 5 having perforate arms 6 for receiving fastening screws 1 thatpass through apertures provided in the inner edge portions of the lensessubstantially mid-way of the height thereof. The outer edge portions oflenses 2 are also perforated substantially midway of the height ofeachlens in the usual way for receiving additional fasteners I that alsopass through the perforate arms 8 of the temple end piece straps 9..

Each of the temple end piece straps 9 is provided with an outwardlyextending boss I 0, shown as of cylindrical shape, which boss isprovided with a spherical seat or receiving recess or socket II forreceiving the ball portion I2 of the temple end piece yoke I3. The outerportion of the boss I0 surrounding the seat or receiving recess II, isadapted to be spun or squeezed over somewhat so as to overlie the ballend portion I2, i. e. beyond the mid plane of the ball, therebyretaining the ball end portion I2 within the recess II of boss I0. Theyoke I3 is provided with the usual temple screw I4 to which the templeis hingedly connected. The ball end portion I2 of the yoke I3 cooperateswith seat I I to provide a universal connection between the strap 9 andthe yoke I3, thereby enabling the temple 2!! to be set at any. desiredangle with respect to the strap 9, to greatly facilitate the fitting ofthe glasses to the wearers face and head.

In order to secure the ball end portion I2 in a selected adjustedposition within the recess II, a screw I4 is provided which is threadedthrough an aperture I5 provided in the temple end piece strap 9, thesaid aperture I5 extending outwardly from the bight portion of the strap9 and lying substantially in the central vertical plane of the lens 2.The free end N5 of screw I4 is pointed so that the optician may engagethis pointed end against the ball end portion I2, after the temple hasbeen adjusted as desired, thereby locking the ball end portion againstturning.

The screw I4 would ordinarily be of steel or other hard material whereasthe ball end portion i2 is ordinarily of precious metal alloy, and hencesofter than the screw l4 so that the pointed end of the screw willreadily pierce the surface of the ball end portion l2 and form a slightdepression therein, thereby serving to positively hold the ball endportion and hence the yoke [3 from above or below the mid height of lensowing to the fact that the ball end portion I21 cooperates with seat IIto provide for the universal positioning of the temple 20 withrespect'to. th'e strap 9. It will be noted that with screw [47 in" place, thehead of the same is engaged by the lens 2, thereby preventing theaccidental loosening oi the screw.

If desired, the locking screw may by the temple end: piece yoke memberinsteadv of by the lens strap. Such a construction isillustrated inFigs. 4 to 6. Parts of these figures which are similar to the parts ofthe previous figures are similarly numbered. In Figs. 4. to- 6 the yokeI3 has a somewhat modified shape in plan from the form shown. intheprevious figures and is provided with a threaded aperture H forreceiving the locking screw I8. The screw i8 extends through the ballend portion l2 and is adapted to engage the surface of receiving recessII. The screw. l8, being of harder material thanthat of the boss I0,readily forms a slight depression in this boss within the recess II, asshown in Figs. 4 and 5, thereby serving'to lock the ball end portion l2:in any desired position within the recess II.

The form of the invention shown in Figs; 4. to 6' mayv be used whereverthe form shown in the previous figures is employed and is somewhateasier to fit inasmuch as the screw "it is readily accessible with the.regular lens, 2 in place. Although the invention has been shown appliedto spectacles of the rimless type, the same is equally applicable tospectacles having rims.

As many changes could be made in the above construction and manyapparently widely different' embodiments of this. invention could. bemade without departing from the scope there-' of, as defined by thefollowing claims, it. is in:- tended thatall matter contained in theabove description or shown in the accompanying. drawing shall beinterpreted as illustrative and not in a limiting sense.

I. claim: a

1. A temple end piece for spectacles and eye'- glassescomprising, a lensstrap for attaching to be carried a lens, said strap having a sphericalreceiving re cess therein, a yoke member providedwith a ball end portionuniversally seated in said recess, locking means 'for securing said ballend portion in adjusted position within said recess, and a templehingedly connected to saidryoke member.
